EDIT2: Wired connection.EDIT3: While supposedly streaming, Bitrate keeps changing from 0 to 1, and Max achieved is 6.EDIT4 (April 2nd): Managed to get a 6 years old notebook, really basic when it was bought, pretty outdated, onboard graphics, pentium dual core around 1,2Ghz, 4GB ddr2 ram, running windows XP. Same router as my main desktop, and it works flawlessly. Ok, so the problem is on windows 7 itself, is there anything I can do?

Of course I tried everything related, whether oficial or not, things that worked out or even steps people tried and didn't work for them, I tried too. I'm out of ideas. Thanks for the time reading this.
